To etZZ whom it may concern:

Beitknown that I, FRANZ Gnrzsorin, asubject of the Emperor ofGermany,and a resident of Freiberg, in the Kingdom of Saxony, Germany,have invented certain new and useful 1m provemeutsin Composition forMaking Artificial Leather Fabric, of which the following is aspecification.

The present invention has for its object a new composition for makingartificial leather fabric, which fabric shall be cheaper than ordinaryleather, but yet equally serviceable for use in the manufacture ofvarious articles-suoh, for instance, as driviug-helts.

The fabric consists in a strong felted material, preferably composed ofhemp or of camels hair, which is treated with my new composition,consisting of a mixture of glue, Wax, oil, turpentine, and alcohol, ashereinutter specified.

In making the mixture the following proportions are preferred, thoughthey may be varied somewhat, if desired: glue, one kilogram; was, onekilogram;- oil, one-half kilogram; turpentine, one-fourtl1 kilogram;alcohol, one-hall liter. glue is allowed to dissolve in thirty liters ofWater during one and a half days. The was, oil, and turpentine are thenadded and the mixture is boiled. Finally when the whole has cooled offunder continuous stirring the alcohol is added and the mass is stirredto insure a perfect dissolution and thorough combination of alltheiugredients.

The felt is immersed in this mixture, heated to 80 ceutigrade, and isleftuntil it is thoroughly impregnated therewith. It is then passedbetweenrollers to press, stretch, and dry it and is finally varnished orlacquered;

The product resembles ordmary leather and stretch.

The object of using the materials specified is as follows: The glueserves to produce an intimate combination of the separate mole cules.The wax (preferably beeswax) serves to make the material, andconsequently the belt, 1nore pliable. The oil (preferably linseed-oil)serves. to protect the material against the influence of the atmosphere,more especially against humidity, rain, duo. The tur: pentiue serves toprotect it against possible destruction by insects. The alcohol servesto dissolve theother ingredients.

. 4 1 is as strong as the latter and less liable to Having thusdescribed my invention, What 5 5 I claim, and desire to secure byLetters Pat; out is--- a A: composition for making artificial leatherfabric, consisting of a mixture of glue, one part; wax, one part; oil,one-half part; turpentiue, one-fourth part, and alcohol,'onehalfpart, asand for the purpose set forth.

Signed by me at Dresden, Saxony, this 19th day of September, 1898.
